Abstract
A slide fastener includes a pair of left and right fastener tapes; and a pair of element rows including a plurality of fastener elements that face edge portions of the fastener tapes on sides facing each other along a length direction of the fastener tapes, and to which a slider that engages with the pair of element rows is slidably attached. The fastener element is made of a metal, a water-repellent layer made of a water-repellent agent is provided on the fastener tape, and adhesion of water to the fastener tape is prevented by the water-repellent layer.
Claims7
A slide fastener, including a pair of left and right fastener tapes;
- and a pair of element rows including a plurality of fastener elements that face edge portions of the fastener tapes on sides facing each other along a length direction of the fastener tapes, and to which a slider that engages with the pair of element rows is slidably attached, wherein
- the fastener elements are made of a metal, a water-repellent layer made of a water-repellent agent is provided on the fastener tapes, and adhesion of water to the fastener tapes is prevented by the water-repellent layer,
- a coating layer made of a coating agent is provided on the fastener elements, and the fastener elements have a rust preventive effect,
- the coating layer is made of a first polymer, and
- the water-repellent layer is made of a second polymer.
A method of manufacturing a slide fastener comprising:
- forming individual fastener elements made of a metal;
- forming a fastener stringer by attaching the fastener elements to one edge portion along a longitudinal direction of a long fastener tape;
- forming a water-repellent layer by adhering a water-repellent agent to the fastener elements and the fastener tape;
- and
- attaching a slider to a pair of the fastener stringers, wherein
- a coating layer is formed on an element substrate made of a stainless steel to form the fastener elements having a rust preventive effect,
- the coating layer is made of a first polymer, and
- the water-repellent layer is made of a second polymer.
